' CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 746,728, dat d D b 15, 1903. Application filed July 25, 1903. $erial No. 167,015. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL MORRIS, a citizen of the United States, residing at Newark, in the county of Licking and State of Ohio, have invented certain new and useful Improvements in Car-Couplings and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to whichit ap pertains to make and use the same.

The object of this invention is to provide an improved automatic coupling of simple and economical construction adapted to effect the coupling of cars as well upon curved as upon straight tracks.

The invention is embodied in the construction herein shown and described, the particular features of novelty being pointed out in the claims.

In the accompanying drawings, illustrating one form of the invention, Figure l is a front elevation with the knuckle removed. Fig. 2 is a sectional view horizontally of the drawhar, the knuckle being in full plan view. Fig. 3 is a perspective view of the knuckle. Fig. 4 is a perspective view of the pin. Fig. 5 is a plan illustrating the position of the knuckle inthe draw-head when the cars are coupled on a curved track. Fig. 6 showsa plan depicting the position of the knuckle when the cars are coupled on a straight track. Figs.

'7 and 8 are front views, the former showing the position of the-pin when the cars arecoupled on a'curved track and the latter when on a straight track.

Like characters of reference in the several views designate corresponding parts.

1 designates the drawbar,and 2 the knuckle, pivoted on a pin 2 in the draw-head, as usual. The knuckle viewed horizontally has a wedgeshaped arm 2 and a finger 2" extending angularly inward from the arm 2 said finger to reach behind shoulders 1 back of the main cavity of the draw-head. The arm 2 has at its corner on the outward side a locking edge 2 This arm is also notched, as indicated, at the upper end of this corner to form a locking edge 2 and a seat or shoulder 2 for the locking-pin,as hereinafter set forth. The edge 2 is located forward of the edge 2.

3 designates a spring, secured in the cavity shoulder 2 of the draw-head behind the knuckle, tending to throw the arm 2 and the knuckle outward to uncoupled position.

4 designates the locking pin. This pin is cut away, as indicated, to form two horizontal shoulders 4 and 4", the shoulder 4* being located higher on the pin than the shoulder 4 Between these shoulders is a vertical knuckle-locking edge 4. The pin 4 works vertically hut uon-rotatively in a hole 5 in the draw-head adjacent the path of movement of the end of the arm 2* and finger 2 and the pin is operated in its downward movement bygravity or, if desired, by a spring ,(not shown) and in its upward movement by hand.

The operation is as follows: In uncoupled I position the pin is constantly supported on the upper face of the finger 2 by the resting of the shoulder t thereon, When the finger 2 is thrown in by an approaching coupler, the pin falls and the locking edge 4 thereof engages the edge 2 of the arm 2 the shoulder a resting on the seat 2. This engagement of the locking edges, as just described, will couple the cars on a curve and the knuckle will be in the position indicated in Figs. Sand 7, and when the cars run onto a straight track thefinger 2 will be forced farther in by the straightening of the cars with respect to each other and the lockingpin will drop until the locking edge 4: thereof engages the corner 2 or looking edge of the arm 2 When uncoupled cars are run together on a straight track, the locking-pin of course falls at once to the position where the only way in which the operation may take place, because the locking edge 4 between the shoulders can be made shorter and the pin supported by the shoulder 4: on the The construction shown, however, is preferred because it gives a good locking edge 4.

Should the pivot-pin 2 of the knuckle be accidentally cut 0% because of the heaviness of the load, or should that pin be lost While the cars are coupled the cars will still remain coupled because of' the engagement of the finger 2 with the shoulders 1" conjointly with the engagement of the locking-pin 4.- with the arm of the knuckle.

What I claim, and desire to secure by Letters Patent, is I l. The combination in a car-coupling of a pivoted knuckle having an arm with two locking edges, one forward of the other, a spring tending to hold said arm outward, and a lockingpin having shoulders 45 and 4 and a locking edge 4 between said shoulders to engage the locking edges on the aforesaid arm automatically and successively.

2. The combination in a car-coupling of a SAMUEL MORRIS.
